Characters don´t instantiate, need some help.

I'm making an rts game and I want to instantiate a selected unity (based on the toggle that is On), in the spawnPosition. Basically it doesn't work. You have the code below.

Code (CSharp):

1. void Update()
2.     {
3.         if (toggle1.isOn)
4.         {
5.             RaycastHit hitInfo;
6.             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
7.  
8.             if (!EventSystem.current.IsPointerOverGameObject())
9.             {
10.                 if (Physics.Raycast(ray, out hitInfo))
11.                 {
12.                     if (hitInfo.collider.tag == "CubePrefab")
13.                     {
14.                         if (Input.GetMouseButton(2))
15.                         {
16.                             Vector3 spawnLocation = new Vector3(Input.mousePosition.x, 1.5f, Input.mousePosition.y);
17.                             Instantiate(unit1, spawnLocation, Quaternion.identity);
18.                         }
19.                     }
20.                 }
21.             }
22.         }
23.         else if (toggle2.isOn)
24.         {
25.             RaycastHit hitInfo;
26.             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
27.  
28.             if (!EventSystem.current.IsPointerOverGameObject())
29.             {
30.                 if (Physics.Raycast(ray, out hitInfo))
31.                 {
32.                     if (hitInfo.collider.tag == "CubePrefab")
33.                     {
34.                         if (Input.GetMouseButton(2))
35.                         {
36.                             Vector3 spawnLocation = new Vector3(Input.mousePosition.x, 1.5f, Input.mousePosition.y);
37.                             Instantiate(unit2, spawnLocation, Quaternion.identity);
38.                         }
39.                     }
40.                 }
41.             }
42.         }
43.     }

I have a two public game objects, and two public toggles created also.

 

You most likely need to convert your mouse position from screen space to world space.
This can be accomplished by using Camera.ScreenToWorldPoint and supplying

Input.mousePosition

as the parameter.
